Answer:
Conversion and substitution
Step-by-step explanation:
One way to find out if the expression is true, we can convert all the percentages into their decimal equivalence.
60% = 0.6
10% = 0.1
6% = 0.06
Now let's substitute the values.
0.06 = 0.6 x 0.1
0.06 = 0.06
Since 0.06 is equal 0.06, this then proves that it is true.
ABD = 40, CD = 143, X = 43.5, AB = 140, BC = 126
Sorry I'm in a hurry right now so I can't give explanations but I hope this helps!
